Organelle morphogenesis by active remodeling
N. Ramakrishnan, John H. Ipsen, Madan Rao +1
Intracellular organelles are subject to a steady flux of lipids and proteins through active, energy consuming transport processes. Active fission and fusion are promoted by GTPases…
Membrane mediated aggregation of curvature inducing nematogens and membrane tubulation
N. Ramakrishnan, P. B. Sunil Kumar, John H. Ipsen
The shapes of cell membranes are largely regulated by membrane associated, curvature active, proteins. We use a numerical model of the membrane with elongated membrane inclusions,…
Role of disclinations in determining the morphology of deformable fluid interfaces
N. Ramakrishnan, John H. Ipsen, P. B. Sunil Kumar
We study the equilibrium shapes of vesicles, with an in-plane nematic order, using a Monte-Carlo scheme and show that highly curved shapes, like tubes and discs, with a striking si…
Modeling anisotropic elasticity of fluid membranes
N. Ramakrishnan, P. B. Sunil Kumar, John H. Ipsen
The biological membrane, which compartmentalizes the cell and its organelles, exhibit wide variety of macroscopic shapes of varying morphology and topology. A systematic understand…
Monte Carlo simulations of fluid vesicles with in plane orientational ordering
N. Ramakrishnan, P. B. Sunil Kumar, John H. Ipsen
We present a method for simulating fluid vesicles with in-plane orientational ordering. The method involves computation of local curvature tensor and parallel transport of the orie…
